However, this detection method can only detect light leakage of blind holes and cannot simultaneously detect the appearance of blind holes. This results in multiple subsequent inspections, which are prone to omissions and affect production efficiency. Utility Model Content

[0004] In view of the fact that existing blind hole light leakage detection equipment can only detect whether blind holes leak light, but cannot perform blind hole appearance inspection, resulting in the need to perform multiple subsequent inspections, affecting production efficiency, and easily causing the omission of inspection items, this utility model provides a screen blind hole detection mechanism.

[0031] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0032] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. This disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0033] Reference Figures 1-3 , Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is another structural schematic diagram of the present invention; Figure 3 This is another structural schematic diagram of the present invention. A screen blind hole detection mechanism includes: a detection platform 21, which transports the screen assembly to be tested; a light leakage detection component 22 is provided on the transport path of the detection platform 21 to perform light leakage detection on the blind holes of the screen assembly received by the detection platform 21; and an appearance inspection component 23 is provided on the transport path of the detection platform 21 to perform appearance inspection on the blind holes of the screen assembly received by the detection platform 21.

[0034] This screen blind hole inspection mechanism, by setting appearance inspection components and light leakage inspection components on the conveying path of the inspection platform, enables the inspection of light leakage and appearance of blind holes in the screen assembly to be carried out separately when the blind holes in the screen assembly are inspected by the inspection mechanism. All inspections of blind holes can be completed at one time, improving inspection efficiency. This avoids the situation where traditional blind hole light leakage inspection equipment can only inspect blind holes in the screen assembly, and other equipment needs to be replaced for separate inspections, which affects production efficiency and is prone to omission of inspection items.

[0035] Rereference Figure 2The testing platform 21 includes a testing drive 211 and a testing carrier 212. The testing carrier 212 is connected to the driving end of the testing drive 211 and carries the screen assembly to be tested. The testing drive 211 drives the testing carrier 212 to move, thereby transporting the screen assembly to be tested carried on the testing carrier 212.

[0036] Specifically, the detection drive component 211 consists of two parts: a drive part and a guide part. The drive part is mainly an electric motor, and the guide part is mainly a screw. The electric motor drives the screw to rotate forward and backward, thereby conveying the detection carrier component 212 connected to the guide part, thus achieving the effect of conveying the screen assembly to be detected.

[0037] Reference Figure 4 , Figure 4 This is a schematic diagram of the testing platform structure of this utility model. The testing support 212 includes a ribbon cable crimping fixture 2121 and a limiting member 2122. The ribbon cable crimping fixture 2121 is connected to the driving end of the testing drive 211 and supports the screen assembly. It is also electrically connected to the ribbon cable terminal, thereby illuminating the screen assembly and ensuring the detection effect of light leakage through blind holes. The limiting member 2122 is connected to the ribbon cable crimping fixture 2121 and limits the screen assembly supported on the ribbon cable crimping fixture 2121. The limiting member 2122 is pneumatically driven to limit the screen assembly supported on the ribbon cable crimping fixture 2121, ensuring that the screen assembly is in a fixed position each time it is placed on the ribbon cable crimping fixture 2121.

[0038] Reference Figures 5-8 , Figure 5 This is a schematic diagram of the structure of this utility model; Figure 6 This is another structural schematic diagram of the present invention; Figure 7 This is a schematic diagram of the terminal pressure head structure of this utility model; Figure 8 This utility model Figure 1Enlarged schematic diagram of the structure at point A. The cable crimping fixture 2121 includes a crimping support platform 21211, a terminal interface 21212, and a terminal crimping head 21213. The crimping support platform 21211 supports the screen assembly. When the screen assembly needs to be tested, it is placed on the crimping support platform 21211 manually or by a robotic arm. The terminal interface 21212 is connected to one end of the crimping support platform 21211 and contacts the terminal portion of the screen assembly. The screen assembly is placed on the crimping support platform 21212. When 11 is in position, the terminal portion of the screen assembly falls precisely on the terminal interface 21212; and the terminal pressure head 21213 is connected to the end of the terminal interface 21212 away from the pressing support platform 21211, and controls the terminal portion of the screen assembly to move closer to and away from the terminal interface 21212. The terminal pressure head 21213 applies pressure to press the terminal portion of the screen assembly into a state where the terminal portion engages with the terminal interface 21212, thereby powering on the screen assembly and facilitating lighting detection.

[0039] The ribbon cable crimping fixture 2121, by setting a terminal interface 21212 and a terminal crimping head 21213, allows the screen assembly to be placed on the crimping support platform 21211 during screen assembly transport by the screen assembly transport assembly, with the ribbon cable terminal precisely positioned at the terminal interface 21212. Then, pressure is applied to the ribbon cable terminal by the terminal crimping head 21213, which connects the ribbon cable terminal to the terminal interface 21212, thereby lighting up the screen. This facilitates the detection of resolution, contrast, and light leakage, avoiding the need for manual pressing to light up the screen in traditional screen assembly lighting tests, which is time-consuming, labor-intensive, affects lighting efficiency, and is prone to scratching the screen, affecting screen quality.

[0040] Rereference Figures 7-8 The ribbon cable crimping fixture 2121 also includes a movable member 21214. The movable member 21214 is connected to one end of the terminal crimping head 21213 and is located at the end of the terminal interface 21212 away from the crimping support platform 21211. The movable member 21214 supports the terminal crimping head 21213 above the terminal interface 21212. The movable member 21214 controls the terminal crimping head 21213 to apply pressure to the terminal and controls the movement of the terminal crimping head 21213. This ensures that there is a certain distance between the terminal crimping head 21213 and the terminal interface 21212 when the screen assembly is placed on the crimping support platform 21211 and when the screen assembly is removed. This allows the terminal part to contact the terminal interface 21212 on its own when the screen assembly is placed on the crimping support platform 21211, without being blocked by the terminal crimping head 21213.

[0041] The ribbon cable crimping fixture 2121 also includes a rotating shaft 21215, which passes through the movable part 21214 and the terminal crimping head 21213. The terminal crimping head 21213 rotates around the rotating shaft 21215 to apply pressure to the terminal in the direction of the terminal interface 21212. This allows the terminal part of the screen assembly to be connected to the terminal interface 21212 by rotating the terminal crimping head 21213 counterclockwise around the rotating shaft 21215. When the terminal crimping head 21213 rotates clockwise around the rotating shaft 21215, the pressure applied to the terminal part of the screen assembly can be released, thereby automatically separating the terminal part of the screen assembly from the terminal interface 21212, automatically de-energizing, and allowing the screen assembly to be removed.

[0042] The moving part 21214 moves towards and away from the terminal interface 21212.

[0043] The movable component 21214 is a solenoid valve, which enables the terminal pressure head 21213 to move closer to or further away from the terminal interface 21212 and to control whether the terminal pressure head 21213 applies pressure to the terminal portion of the screen assembly toward the terminal interface 21212 via electrical control.

[0044] The movable part 21214 is a pneumatic valve, which enables pneumatic control of the terminal head 21213 to move closer to or further away from the terminal interface 21212 and whether the terminal head 21213 applies pressure to the screen assembly terminal portion toward the terminal interface 21212.

[0045] The crimping support platform 21211 consists of two parts: a screen support part 212111 and a ribbon cable support part 212112. The ribbon cable support part 212112 is connected to one end of the screen support part 212111 and is located between the screen support part 212111 and the terminal interface 21212. The screen support part 212111 supports the screen body of the screen assembly, and the ribbon cable support part 212112 supports the ribbon cable of the screen assembly. When the screen assembly is transported and placed on the crimping support platform 21211, the screen body and the ribbon cable are in an unfolded state, and the two are only connected at their ends.

[0046] The pressing support platform 21211 has a detection port 212113 that penetrates through the pressing support platform 21211, and the light leakage detection component 22 performs light leakage detection on the blind hole through the detection port 212113. After the screen assembly is placed on the pressing support platform 21211, the blind hole part of the screen assembly is exactly above the detection port 212113, so that the light leakage detection component 22 located on the side of the pressing support platform 21211 away from the screen support surface can perform light leakage detection on the blind hole of the screen assembly through the detection port 212113.

[0047] The light leakage detection component 22 includes a light-shielding component 221, a first light-emitting component 222, and a light leakage detection component 223. The light-shielding component 221 is installed on the conveying path of the detection platform 21 and shields the screen assembly from light. After the detection drive component 211 conveys the pressing support platform 21211 carrying the screen assembly into the light-shielding component 221, the light-shielding component 221 can block external light, so that no external light shines into the area where the screen assembly is located, thereby ensuring that the light leakage detection of blind holes is not affected by external light. External influences cause light to be emitted. The first light-emitting element 222 is installed on the light-shielding element 221 and illuminates the blind hole area of ​​the screen assembly. This allows the screen assembly to be tested to be illuminated through the first light-emitting element 222, improving the testing effect. The light leakage detection element 223 is installed on one side of the first light-emitting element 222 and detects the blind hole area of ​​the screen assembly. The detection method is to take pictures and analyze whether there is light leakage or whether the light leakage is within the allowable range, thereby determining whether the light leakage test item of the blind hole of the screen assembly is qualified.

[0048] The appearance inspection component 23 includes a front inspection component 231 and a second lighting component 232. The front inspection component 231 is disposed on the conveying path of the inspection platform 21 and inspects the front of the blind hole of the screen assembly carried on the pressing support stage 21211. The second lighting component 232 is disposed on the conveying path of the inspection platform 21 and is opposite to the front inspection component 231, so that the side of the screen assembly away from the front inspection component 231 can be illuminated by the second lighting component 232, revealing the details of the blind hole and improving the inspection effect of the front of the blind hole of the screen assembly.

[0049] The appearance inspection component 23 includes a back inspection component 233 and a third lighting component 234. The back inspection component 233 is disposed on the conveying path of the inspection platform 21 and inspects the back of the blind hole of the screen assembly carried on the pressing support stage 21211. The third lighting component 234 is disposed on the conveying path of the inspection platform 21 and is opposite to the back inspection component 233, so that the side of the screen assembly away from the back inspection component 233 can be illuminated by the second lighting component 232, revealing the details of the blind hole area and improving the inspection effect on the back of the blind hole of the screen assembly.

[0050] The appearance inspection component 23 includes a front inspection component 231, a second lighting component 232, a back inspection component 233, and a third lighting component 234. The front inspection component 231 is disposed on the conveying path of the inspection platform 21 and inspects the front of the blind hole of the screen assembly carried on the pressing support stage 21211. The second lighting component 232 is disposed on the conveying path of the inspection platform 21 and is opposite to the front inspection component 231, so that the side of the screen assembly away from the front inspection component 231 can be illuminated by the second lighting component 232, thus revealing the fine details of the blind hole area. The back detection component 233 is set on the conveying path of the detection platform 21 and performs detection on the back of the blind hole of the screen assembly carried on the pressing support stage 21211. The third lighting component 234 is set on the conveying path of the detection platform 21 and is opposite to the back detection component 233, so that the side of the screen assembly away from the back detection component 233 can be illuminated by the second lighting component 232, revealing the details of the blind hole and improving the detection effect on the back of the blind hole of the screen assembly.

[0051] Furthermore, by using the front detection component 231, the second light-emitting component 232, the back detection component 233, and the third light-emitting component 234 in conjunction, the appearance inspection of both the front and back of the blind hole in the screen assembly is carried out, which improves the appearance inspection effect of the blind hole and ensures that no omissions occur.

[0052] Specifically, the light leakage detection component 223, the front detection component 231, and the back detection component 233 are all imaging devices. By taking pictures of the parts to be inspected, the captured photos are analyzed to determine whether the light leakage and appearance of the screen assembly meet the standards.

[0053] Furthermore, the light leakage detection component 223, the front detection component 231, and the back detection component 233 can all be adjusted in position, such as along the driving direction of the detection drive component 211, closer to or farther from the pressing support stage 21211, and closer to or farther from the detection drive component 211. This allows the screen assembly blind hole detection mechanism to be applicable to the detection of blind holes of different sizes, and further ensures the detection quality and improves the detection effect.
